Upon arrival, drop off your gear, grab some pizza, and dive into a whirlwind of exciting, themed hands-on activities! Every program also includes a live-guided tour of the night sky in the Acheson Planetarium, and a chance to explore the universe in our Observatory.

For the Evening program, doors open at 5:30pm for check-in and pizza dinner. The fun kicks off at 6:00pm and wraps up by 9:00pm.

For Overnight programs, enjoy all the fun of our Evening programs, then roll out your sleeping bags and settle in for a night surrounded by our exhibits. Late-night snacks and a movie make the Overnight adventure even more exciting! Doors open at 5:45pm for check-in and pizza; programming begins promptly at 6:15pm and concludes with breakfast and departure by 8am.
